Stage 7 of 16 · GR20 North
The Brèche de Capitellu, above the Capitellu and Melu lakes: the finest lake-view balcony in Corsica.

| Waypoint | Altitude | Km |
|---|---|---|
| Refuge de Manganu | 1,601 m | 0 km |
| Brèche de Capitellu | 2,225 m | 2.9 km |
| Refuge de Petra Piana | 1,842 m | 8.3 km |
The climb from Manganu is sustained, over slabs and scree, up to the Brèche de Capitellu (2,225 m). On the other side, the view plunges down to the Capitellu and Melu lakes, often still fringed with snow in June: one of the most famous panoramas on the GR20.
The trail then follows a long balcony traverse, with a few chain-equipped sections, above the Restonica valley. The final section leads to the Petra Piana hut, set at 1,842 m at the foot of Monte Rotondo.
Early in the season, snowfields can make the gap tricky: the PNRC then advises crampons, an ice axe and a rope.
4 water points listed on this stage and 1 tricky section (chains, ladders, exposed steps). Springs can run dry in late summer: ask the hut wardens and treat the water if in doubt.
